OSCAR FREDRIK KARLSSON, OF SODERTALJ'E, SWEDEN;

WATER-CLOSET.

Application filed May 24, 1924, Serial No. 715,669, and in SwedenApril 11 1924.

The invention relates to improvements in water closets, in which the flushing tank with float and valve are brought together into one contracted arrangement, and the objects of the improvements are to attain lower costs by eliminating the separate flushing tank with its lead piping, atthe same time effecting the flushing of the receptacle practically noiseless and with a thorough cleaning of the same without any waste of water.

One form of the invention is illustrated in the accompanying drawing, in which:

Fig. 1 is a vertical section of the arrangement with the upper parts, the seat and cover, removed. Fig. 2 is an outside view of the arrangement in Fig. l seen from above.

The water closet receptacle 1 is of somewhat larger size from the front to the rear than common water closets. It is filled with water up to a certain distance from its upper edge, and a container 2 is swimming in it on account of its displacement. This container 2 is narrowing downwards forming,

a mouth 3 of the same or nearly the same diameter as that of common W. C. receptacles. The mouth 3 conveniently widens downwards as shown, forming a collar. Over this collar is turned a packing 41 of some soft or elastic material, as rubber or the like, in the shape of a conical cap or similar, whose lower end is turned over the upturned neck 5, of the discharge 6, which may be provided in the usual way with a water trap. The flushing takes place by immersion of the container 2 below the surface of the water in the receptacle 1. The water then rushes over the brim of the container 2 simultaneously from all sides, bringing about a thorough flushing of the Whole inner surface of the container, and a speedy discharge of the contents, practically noiseless. The immersion of the container 2 may be effected by the help of any suitable device. A good design of such a device is shown on the drawings.

7 is a strap, placed around the foot 21 of the apparatus. The strap is pivotedly connected at its rear to a rod 8, that passes through the said foot 21. At one (or both) side of the strap 7 is a (or two) lever 10 givotedir cennected to the strap at 9- he is inclined upwards and bat Ii -ra part of the receptacle 1.

2. These levers are on their front ends provided with a projection 16 or the like, ex tending inwards against the container 2. These projections each engage a slot 15 in a boss or ear on the outside of the container 2.

The device acts in the following way:

By treading on the strap 7 the lever 12 is pulled down by the connecting lelver 10. Together with the lever 12, the levers 1 1 will be turned downwards, as they are'firmly connected by the same rod 13. The projections'16 on the levers 14 will then press down the container 2 below the Water surface. By thisaction the projections move backwards in the slots 15, which must be done with the smallest possible friction, the container otherwise being pulled backwards. The water now rushes into the container simultaneously from all sides and the flushing of the container is being done.

In the back part of the receptacle 1 the usual device for regulation of the water level is attached. This device may be of any known construction. The fact, however, that it has been removed from its former elevated place, and located within the receptacle itself, is one of the characteristics of this invention, constituting one of its advantages compared with hitherto known devices.

In the drawing 17 is the float, which acts upon the valve 19 in the water inlet 20, through the. rod 18.

As shown, the receptacle, if made out of china, can be cast in one piece with the foot 21.

The invention is not limited only to the shown form, but is susceptible of various changes, if only the essential of the invention is maintained.

I claim:

1. A water closet comprising an inner basin; movably connected at the bottom to the discharge andarranged in an outer receptacle far its water; the width of I... My

and mechanical means for depressing the inner basin. during the Whole of the flushing stroke to allow flushing Water to overflow simultaneously from all sides into the inner basin.

2. A water closet as set forth in claim 1, wherein the said inner basin is connected to the discharge by means of a watertightand flexible connection and arranged floating on the water in the outer receptacle.

3. A water closet as set forth in claim 1, and provided with a float 0n the water in the said outer receptacle in combination with a Water inlet valve operatively connected to said float. v
